MONOLITHIC CONCRETE BLOCKS ADAPTEl) '10 SNUGLY FIT THE RAILS.

To all whom it may concern;

Be it known that I, ADOLPHE GARRIVIER, a citizen of the Republic ofFrance, and a resident of 56 Rue des Chalets, Toulouse, France, haveinvented new and useful Improvements in Monolithic Concrete BlocksAdapted to Snugly Fit the Rails, of which the following is adescription.

The present invention relates to monolithic concrete blocks orpavements, with inner metallic reinforcement bars, for use in theconstruction of railway and tramway tracks, said blocks having such aform as to snugly fit the exterior profile of the rail, on both sidesthereof, and being provided with recesses for housing the fish-plateswith their bolts and the rail tie-bars maintaining the normal gage ofthe track.

The annexed drawing shows, by way of example, a perspective view of arail fitted with two blocks constructed according to the presentinvention.

On both sides of each rail a of a railway or tramway track are arrangedmonolithic concrete blocks or pavements, the one, b, outwardly of therail, the other, 0, on the interior side thereof; said blocks areprovided with inner metallic reinforcement bars, respectively b and 0Said blocks snugly fit the external profile of the rail and are of ashape corresponding to the base, to the web and to the head of the rail,so as to engage exactly every part thereof. The blocks substantially areof the same width as the usual paving-stones, but preferably are of agreater length; their size may be varied according to the kind of railwith which they are to be used.

In the monolithic blocks for use at the joints of rails, recesses (Z areprovided for the fish-plates e and their bolts e in the face of theblocks adapted to fit the web of the rail, said recesses having the sameheight as the fish-plates and having a depth equal to the totalthickness of the fish-plates and of the head of the bolt or of thescrew. The holes of said recesses are filled with a fatty body in orderto prevent wear by rust of Specification of Letters Patent.

Application filed June 1, 1916. Serial No. 101,121.

against the rails of a track, at the points where said rails areconnected together by tie-bars, are provided grooves 7, whose width isequal to the thickness of said tie-bars; the block is laid between therails, care being had to engage the tie-bar 9 into the groove f; theblock is then pushed against the interior face of the tie-bar by slidingon said rail.

Obviously there may be given different shapes to the blocks in order topermit their engagement with the rails at the curves, at theswitch-points, etc.

These blocks, snugly fitting on each side the profile of the rail, giveto the track a greater strength and a more complete stiffness; theyfurther prevent water infiltrations between the rail and the adjacentpaving-stones and furnish a good roadway for the carriages whose gage isnot exactly the same as the gage of the tramways tracks.

What I claim is:

1. A paving block of the type described, comprising a monolith having aface shaped to the profile of a rail but recessed on this face toreceive a fish-plate and its securing bolt together with rust-preventingmaterial in said recess in the assembled rail and block, and surroundingthe bolt end to prevent rusting of the latter.

2. A paving block of the type described, comprising a monolith having aface shaped to the profile of a rail, and transversely grooved on itsbottom face to receive a tie bar extending from the rail.

3. A paving block of the type described, comprising a monolith having aface shaped to the profile of a rail but recessed on this face toreceive a fish-plate and its securing bolt, and transversely grooved onits bottom face to receive a tie bar extending from the rail.

4. A paving block of the type described, comprising an interiorlyreinforced cementitious monolith having a face shaped to the profile ofa rail but recessed on this face to receive a fish-plate and itssecuring bolt, and transversely grooved on its bottom face to receive atie bar extending from the rail.

5. A paving block of the type described, having a face fitting againstthe side of a rail and transversely grooved in its lower face to receivea tie bar on which said block may be temporarily supported.

6. A paving block of the type described,
